[Histonet] Stain and pos control for copper

[Malam Jacqueline]

I wonder if anyone with experience of copper stains can help me. We very
rarely get asked to demonstrate copper and I know of only one positive case
of Wilson's disease in 15 years which we were able to use as a pos control.
We have just had another request. There was barely any control tissue left
and both the test and control was neg. when stained with rhodanine. Two
questions - is rhodanine the best stain, and what can we use for a pos.
control?
All ideas gratefully received!
